To aZZ whom it may concern:

Be it known that we, the Honorable Sir CHARLES ALGEnNoN PARsoNs, K. O.B., a

subject of the King of Great Britain and Ireland, and residing at HeatonWorks, Newcastle-upon-Tyne, and STANLEY SMITH Coon, a subject of theKing of Great Britain and Ireland, and residing at Turbinia W'orks,lVallsend on-Tyne, both in the county of Northumberland, England, haveinvented certain new and useful lmprovements in Condensing Apparatus, ofwhich the following is a specification.

This invention relates to improvements in condensing apparatus of thetype in which a turbine or like chamber exhausts into a condenser havingordinary exhausting means connected thereto and to said cham her, and inwhich augmentor means for increasing the degree of vacuum in thecondenser are connected to the conduit leading from the condenser to theordinary exhaustlng means at the level to which the condensed fluid ispermitted to rise' within the said chamber. In such an arrangement whenthe condensed and non-condensed vapors delivered from the augmentormeans are withdrawn by the ordinary exhausting means it is found thatthe non-condensed vapors are liable to return to the inlet of theaugmentor means instead of passing to the ordinar exhausting means, thusreducing the efficiency of'the plant. 0

The object of the present invention is to overcome this disadvantage,andto provide an improved condensing plant ofthis type.

The invention consists in condensing ap-.

paratus of the above type in which a device such as a liquid seal isprovided in the conduit between the outlet from the augmntor means andthe inlet to the ordinary exhausting means to prevent the return of thenoncondensed vapors to the inlet of the augmentor means.

Referring now to the accompanying draw ing: Figure l is a sectional viewof condensing apparatus arranged according to the present invention,while Fig. 2 is a sectional viewof a modified form of the apparatus. v

'Theinvention also consists in the improved condensing apparatushereinafter described.

One method of carrying the invention into effect is illustrated by wayof example as applied to the condensing apparatus illustrated insectional elevation in Fig. 1. In this arrangement a steam turbine aexhausts steam into a conduit Z) leading to a condenser c,'fromwhich'the water of condensation is removed through a conduit (1by'ordinary exhausting means e, which usually consist in the ordinarytype of wet air pump used in su'ch plant, and which in additionwithdraws water of'condensation from the turbine chamber a by means ofthe pipe connection f.

The degree of vacuum thus produced in the condenser c is increased by.augmentor means g, forexample a jet and condenser which are connectedto the condenser c by the conduit h. For the purpose of preventing thewater of condensation rising to an undesirable at the levelm/m, to whichsuch water to be permitted to rise within the turbine chamber. In suchan arran ement, however, 4

it has been found that i the augmentor means 9 discharge through-a pipeconnection it leading to'the inlet of the ordinary exhausting means e,the non-condensed vapors forming part of'this dischargeareliable to passupward and through/theg'pipe connection is to the inlet of the augmentormeans instead of passing directly to the inlet of the ordinaryexhausting means e. In this way the efliciency of the condensing plantis considerably reduced. According to the present invention, however,this difficulty is overcome by arranging in the conduit at between theoutlet of the augmentor- ,means 9 and the inletto the ordinaryexhausting means 0, a devicewhich prevents the noncondensed vaporsdischarged from the augmentor means being returned to the inlet thereof.Such a device may consist,

for example, in an outer closed vessel p, which forms part of theconnection between the outlet of the augmentor means 9 and the inlet tothe ordinary exhausting means 6.

Direct communication between the main condenser c and-the ordinaryexhaustin means e is provided by extending the vesse 79 some distancebelow the level rr of the inlet valves of the exhausting means 6. In.

this way the condensed vapor discharged from the augmentor means 9 willbe col-' reea lected in the vessel 12, and form a m that rising to anundesirable height in the t-ur-' binechamber a.

In the case of condensing apparatus having between the main condenser0831(1616 ordinary exhausting means 0 a single conduit with a branchconnection is to the aug mentor means 9 as shown in Fig. 2, the conduits is extended so as to project within the vessel 22 to the requireddistance below the level of the condensed vapor collected therein. As inthe previous arrangement any noircondensed vapors discharged from theaugmentor m ans aicdelivered intx) the liquid sealed space 9 in thevessel p, from which they are withdrawn directly by the ordinaryexhausting means 6, and prevented from passing back to the inlet of thenag-mentor means g while the condensed vapors collected in the vessel 79may still overflow into the conduit 76 for the purpose ct preventing thecondensed fluid within the turbine chamber a rising above thepredetermined level mm.

Obviously the device for preventing the passage of non-condensed vaporsfrom the conduit n to that leading to the inlet of the augmentor means 9may take many forms, it being only essential for the purpose ofthepresent invention that such a device allows only the condensed'vaporsdischarged from the augmentor means to return to the inlet of the latterwhen required.

Having now described our invention, what we claim as new and desire tosecure by Letters Patent is 1. An apparatus for obtaining a high degreeof vacuum comprising in combination a motor, a condenser receiving thefluid discharged from said motorfeahausting means,

a pipe connection between the condenser and the exhausting means, adrainage pipe connection from the motor to the exhausting means,augmentor means having a connection to the connection between thecondenser and exhausting means, said connection being made at the levelto which condensed fluid is permitted to rise within the motor, a connection conveying fluid from the augmentor means to the exhausting meansand means by'which any uncondensed fluid which has already passed fromthe augmentor means to the exhausting means is prevented fromcirculating through the other pipe COIIHBC' tions back to the augmcntormeans.

2. An apparatus for obtaining a high de gree of vacuum co nprising incombination a motor, a condenser receiving the fluid discharged from themotor, exhausting means, a pipe connection between the "condenser andthe exhausting means, a drainage pipe connection from the motor to theexhausting means, augmentor means, a pipe connection betweensaidaugmcntor means and the condenser, an overflow pipe cohncctionbetween the latter connection and the'ponneption between the condenserand exhausting means. said overflow connection being connected to theexhausting means pipe connection at the level to which condensed fluidis permitted to rise within the motor, a connection conveying fluid fromthe augmentor means to the exhausting means, and means by whichuncondenscd fiuid'which has already passed from the augmentor means tothe exhaust ing means is prevented from returning to the augmentormeansby Why of said overflow connection.

In testimony whereof, We aflix our signatures in presence oftwowitnesses.
